York S1-024-19082-028 Sequencer Relay

The York S1-024-19082-028 is a field-proven 24V heat sequencer relay engineered for precise staging of electric heating elements and blower motors in residential and light commercial air handlers. This OEM York replacement part features a multi-switch configuration designed to prevent high inrush currents and nuisance tripping by staggering the activation of resistive loads. It operates on a standard 24V AC control circuit and is built with robust terminals to withstand the thermal stresses of repeated cycling. Designed as a direct fit for York model D2CG036N08225A and similar furnace platforms, it ensures that heating stages engage and disengage in the correct order, maintaining consistent discharge air temperatures while protecting the integrity of the HVAC control system components. For contractors looking to restore factory-spec timing in blower and heater sequences, this electric heat sequencer provides the necessary switching reliability and mechanical durability required for demanding 3-wire power systems.

Key Benefits:

• Ensures accurate heat stage sequencing to prevent circuit overloads during unit startup.
• Direct York OEM replacement simplifies installation with matched mounting and terminal footprints.
• Maintains system efficiency by regulating the timing of blower motor and heater element activation.
• Rugged construction rated for 30-amp resistive loads, ensuring long-term duty cycle performance.

Common Questions:

What are the timing specs for this sequencer?
Standard S1 series sequencers typically feature a delay-on timing of 1 to 110 seconds and a delay-off timing of 1 to 110 seconds, though specific timings can vary based on load and ambient conditions.

Can this relay replace an S1-19082-020 or S1-19082-031?
While they share the same base series, you must verify the number of internal switches and the specific load ratings. It is recommended to use the S1-024-19082-028 only where the part number or schematic calls for this exact specification.

Is this sequencer compatible with non-York brands?
While optimized for York, Luxaire, and Coleman equipment, this 24V sequencer can be used in other convection or electric furnaces provided the voltage, amperage, and sequence timings align with the manufacturer's requirements.
